Falk Couplings: What are they and what are they used for


Falk’s couplings have been considered the industry standard for many, many years now. They are renowned for their durability and versatility in a variety of critical applications, with each of the designs having a proven performance record. Just in North America alone, the Falk Steelflex couplings are one of the most frequently requested grid couplings from machinery component distributors. The Falk Wrapflex couplings are also widely sought by many organisations operating in a wide variety of industries around the world.


Falk Steelflex Couplings


There are numerous models of Steelflex coupling which Falk produce, including high-speed, flywheel brakes and controlled torque designs. Each design will have its own specified torque and bore capacities, while a variety of rpm choices should ensure that Falk Couplings fulfil whatever coupling requirements you have. The ‘replace-in-place’ feature of the couplings also ensures that your machinery undergoes only the absolute minimum of downtime while worn parts are being replaced.


Another of the main features and benefits of these Falk couplings is the lubricant that comes with them. It’s called Falk Long Term Grease (usually referred to as LTG) and it lasts for up to five years before needing to be replaced. That’s a guarantee that Falk offers with their special lubrication, as they are sure it will help minimise wear and tear as much as possible.


Overall, the Falk Steelflex coupling is a general purpose design that benefits from a combination of the economical high torque capacity of a standard gear coupling while enjoying the flexible torsion that the Elastomeric range of couplings has (such as the Wrapflex couplings described below). The flexible torsion is important as it enables these couplings to ‘torsionally deflect’ whenever they are subjected to impact, shocks and vibrations, ensuring the continued operation of the machinery despite changing load conditions. In fact, the Falk Steelflex couplings not only absorb impact energies and dampen vibrations, they will also reduce shock loads by up to 30%.


Falk Wrapflex Couplings


These Wrapflex designs are part of Falk’s Elastomeric Couplings range and they are the easiest and most cost-effective coupling for any machinery operating with a low-to-medium torque application. The same ‘replace-in-place’ feature applies here as well, so the replacement of worn parts will not cause any major downtime in machinery operation. This is because none of the motors or drives needs to be removed in order to replace any of the components, thus eliminating any time-consuming realignment.


The flexible design of the Falk Wrapflex couplings improves the tooth on tooth contact while also helping to minimise any potential misalignment during operation. Included in the design are carbon steel hubs for maximum strength and long-lasting polyurethane elements which are extremely tough with excellent wear resistance. They are also resistant to chemicals with around a 95 degrees Celsius temperature rating.


In the most basic terms, Falk Wrapflex couplings are non-lubricated, material-flexing couplings which can be applied to a wide variety of applications across many industries.
